All of the scrapers are so operatively connected that they all may berotated at once by a commo mover.

Hence the primary object of the present invention is to so.improve the pan of 'the prior invention that it may be manufactured andin a more expeditious manner. Moreover, that the improved at a lowercost it is found, in. practice, pan will give better results than thepan of my prior invention.

In carrying out the present invention, the

scrapers are so mounted that they are fixed relative to the plate inwhich the muffin re ceiving cups are mounted aresupported and these cupsfor rotation in the plate and are operatively connected together so thatthey maybe common men simultaneously rotated from a iber or prime mover.This con- 7 struction results. in the simplification of parts and amembers. for

Figure 3 is a perspective view of one of the scrapers; and,

Figure 4 isa perspective section of a layer cake pan embodying thepresent invention.

Referring to the drawings, and more par- 3 inclusive, 5 designates aplate of sheet metal preferably tin or aluminum of any suitable shapeadapted to form the'body portion of the pan. The outer edge of thisplate is rolled over as at 6 to give aefinished edge and the body of theplate 5 is punched out at spaced intervals to provide openings adaptedto cooperate with a corresponding number of cups 7 in which the muflinsare adapted to be cooked.

The plate 5 is preferably formed by stamping up the same and about eachcup opening is formed an upstanding flange 8 which is curved upwardlyand outwardly, as best shown in Figure 2. A flange thus formed has aconcave outer face and a convex inner face.

he cups may be stamped up fromsheet metal, the outer edge oi. the blankbeing bent outwardly and inwardly and terminating in a gear 11 whichextends around the entire circumference of the cup intermediate its topand bottom. This formation of the cups moreover results in providingear-h cup with a beaded or thickened upper edge 12. In assembling thepan, the cups 7 may be readily associated with the plate 5 by forcingthe thickened or beaded upper of each cup through one of the openings inthe plate 5. The parts are so proportioned that the bead 12 of each cuprequires forcing through the corresponding opening in theplate, butafter such bead is passed through the opening the under face thereofseats against the convex surface of the (:0- operating'fiange 8, whilethe upper surface of the gear 11 seats against the underside of theplate 5, so as to hold the pan firmly in position and at the same timepermit of rotation of the cup relative to the plate.

The position of the several cups on the plate 5 in the manner. describedautomatically brings the gears 11 of adjacent cups into mesh, therebyconnecting all of the edge 12 bodying cross arms which ill ' cups andare secured ously, while all of cups together for simultaneous rotationwhich may be imparted thereto by rotating one of the cups throughoscillation of a handle or finger piece 13 associated therewith. Thisfinger piece'maybe formed integral with one cup and bent outwardly underthe beads 6 o l the plate 5; after the manner shown in Figure 2, whereinit will occupy an accessible position to be grasped and: manipulated.

Positioned within each of the cups is a scraper 1dof the character shownin Figure 3. This scraper consists in a stamping emare bent up toconform to the interior of the cups and is of substantially a spidershape. The end of each arm of the spider is curled over as at 15 so thatwhen the spiders are dropped throughthe'cup openings in the plate 5, thecurls l5 may be sprung into engagement with the convex faces of theflanges 3, thereby serving to clamp the scrapers firmly and inproper-"position within the respective cups. The curls 15 of thescrapers may be soldered to the flanges 8 it desired. 7

If the finger piece l3 is now manipulated, all oi. the cups will berotated simultanethe scrapers will remain stationary and in this mannermuiiius may be. readily dislodged from the respective cups andconveniently removed therefrom.

It will be apparent from the foregoing description that the outer end ofearh arm or each spider'is firmly anchored in position adjacent theouter periphery of the respective cups, and the spiders will tightlycling to the walls of the cup at all times so that when the cups arerotated they will operate as scrapers to elliciently tree the imitlinsfrom the cups. In the constr ction of Fig ures 1 to l the ends 01. thespiders are, in eltect, curled over the beaded edges ot the to theflanges S. This is the construction which is preferable in a mudln pan,although I have shown in Fig ure & the general idea as applied to alayer cake pan wherein the plate 5 the. construction of Figure l the pan7 is beaded over at its upper edge and at one 7 integral therewithrection so that it point in its periphery the bead has formed a fingerpiece 16 whiih to extend in a lateral dimay be readily grasped. Thespider 14E has the outer end of its arms connected by an annular ring 15which is curled: over the bead 12 of the pan ant. at one point in thecircumference oil the ring 15' is formed a finger piece 13" which isbent outwardly to extend in a lateral direction and into anaccessibleposition.

The curling over ot the spider ring 15" is so accomplished as to permitof relative rotation between the spider and the pan- 7, so that it thefingers 16 and 13 are grasped, and rotation through degrees-or more isbent outwardly is omitted. Tn

pan and'spider, the cake imparted to the be etliciently scraped withinthe pan 7" may tree from the pan. 7

It will be apparent from the foregoing description that the presentinvention is susceptible to modification in details of constructionwithout departing from the spirit of the invention, the scope oi whichis comrnensurate with the appended claims.
